Abstract

A method and an apparatus for producing crimped filament yarns, said apparatus comprising at least one first twister member and at least one second twister member, each of said twister members having a work surface made of a synthetic rubber having a relatively small friction coefficient therebetween. These twister members are arranged so that their work surfaces cross each other at a selectable angle in contact relationship to provide at least one crossing zone for nipping therebetween at least one thermoplastic filament yarn which is fed to twist this filament yarn between the contacting work surfaces successively and at the same time to urge this filament to discharge from this crossing zone successively as the twister members are driven. This method and apparatus allow filament yarns to be imparted desired false-twisting effect, practically without being damaged and without causing uneven twists, at a high operation rate of 800 - 1000 meters per minute.
